Michael Ford (fanquake)
Michael's funding supports his work as a maintainer as well as his work on the build system, security, and reducing the number of dependencies used in the codebase.
"Brink has created the ideal working environment for Bitcoin protocol engineers to learn and collaborate. Providing full time, long term sponsorship, also means I can focus 100% of my time on contributing to, and maintaining, Bitcoin Core."
Gloria is one of the maintainers of Bitcoin Core, primarily focused on mempool and P2P. She is currently working on package relay (BIP331) and transaction relay policy changes to make pinning attacks more difficult. She also co-runs Bitcoin Core PR Review Club aimed at helping newcomers learn about the codebase and PR review process.
"Brink's grant committee includes engineers who understand the maintenance required of Bitcoin Core and can tell the difference between frankensteining flashy features and architecting a robust protocol. The decision-making process and stability gives me the confidence to spend my time digging into bugs, reviewing large projects, and working on protocol changes like package relay. In addition to supporting educational content like Optech and the PR Review Club, I feel Brink makes an effort foster an internal culture of teaching and learning from each other."
Hennadii has been contributing code and review to Bitcoin Core since 2018. In that time he has become one of the most prolific contributors to the project. Hennadii’s funding allows him to work full time on Bitcoin Core development and review.
"I am deeply grateful to Brink for their unwavering support in enabling me to work on the Bitcoin Core project, review pull requests, and maintain Bitcoin Core GUI and translations. Their consistent support is invaluable to me and has allowed me to contribute to the Bitcoin Core project with confidence and enthusiasm."
Larry reviews and tests Bitcoin Core PRs focusing on correctness, thread-safety, code organization and maintainability, test coverage, logging for problem analysis, and related areas.
"I give Brink enormous credit and respect for beating the bushes to find talent among those who are more on the quiet or humble side, nurturing and supporting us both financially and socially, and turning us into productive contributors. I can't say enough good things about how professional and, honestly, caring everyone I've interacted with at Brink has been to me. Sometimes dreams do come true."
Sebastian's funding supports his code review and testing, improving test coverage, extending the test framework, and improving the networking/P2P and wallet codebases.
"Thanks to Brink's funding I can work a dedicated time per week purely focused on improving Bitcoin Core. In addition to the financial support, the organization allows me to be part of a great community of like-minded "Brinkies" by holding regular tech engineering calls and events, which is a valuable experience to learn from each other."
Vincenzo's funding supports his work adding new features to Core Lightning and reviewing others' pull requests, as well as his ongoing contributions to the Lightning specification.
"The Brink grant program has enabled me to fully concentrate on my work without any financial worries. Moreover, Brink has provided me with the freedom to work independently towards my goals while still keeping me closely connected with the Lightning community. This level of support has made my experience with Brink truly exceptional and has been instrumental in my progress as a developer."
Niklas’ funding supports his work on Bitcoin Core. His focus is on making Bitcoin Core's peer-to-peer code more robust through review, testing and fuzzing.
"Thanks to Brink's support, I have the incredible opportunity to dedicate myself full-time to Bitcoin Core, allowing me to contribute more effectively and collaborate with the other Brinkies in the London office."
Stéphan's grant enables him to continue his review and testing of changes to Bitcoin Core, contribute to Miniscript, and his educational efforts of new Bitcoin developers.
"For many including myself, being able to work together with people makes a significant difference for creativity and productivity. Besides allowing me to work on Bitcoin Core and related education projects full time through the grant program, Brink has gone through significant lengths in enabling developers from across the world to meet and work with each other in-person, whether on a permanent or ad-hoc basis."
Fabian's grant supports his work on investigating innovations enabled by Schnorr signatures, dedicated in-depth code review of important Bitcoin Core initiatives, ASMap development, and alternative code hosting solutions.
"A full-time grant enables me to concentrate on thoroughly reviewing intricate proposals and code modifications, allowing me to grasp their full implications and potential impact on the network."
